Kramer, M, Clark, IE, Jamnick, N, Strom, C, and Pettitt, RW. Normative data for critical speed and D' for high-level male rugby players. J Strength Cond Res 32(3): 783-789, 2018-The critical speed (CS) concept helps characterize the aerobic and anaerobic fitness of an athlete. Rugby players should, hypothetically, have modest CS values but extremely high curvature constant (D') values, yet, normative data are currently unavailable. To develop normative data of CS and D' for high-level male rugby players, a total of 30 male rugby players were recruited from the Eastern Cape of South Africa. All subjects performed the running 3-minute all-out exercise test (3 MT) using global positioning system (GPS) technology to determine CS and D'. The GPS data were used to determine the total distance and velocities performed, and to examine for pacing effects. Summary statistics of mean ± SD are provided. High total running speeds for the initial 150 seconds (S150s = 5.79 ± 0.59 m·s), and total distance (3 MT distance = 871.5 ± 71.9 m) were observed. A total of 13 of 30 subjects surpassed the 300 m D' value (mean D' = 288.2 ± 49.1 m). The CS of the total group was 3.87 ± 0.55 m·s. All 3 MT-derived data were categorized using standard nine (stanine) tables that allowed for the generation of normative data with which future performances, performances across similar sporting domains, and more accurate contrasts across the literature can be compared. Skewing of CS and D' was observed between forwards and backs, therefore, between-group differences in neither CS nor D' were observed (p > 0.05). Comparisons with previous literature indicate that male rugby players have higher CS values than female rugby players. When compared with Olympic distance runners, male rugby players have markedly higher D' values and markedly lower CS values. The 3 MT provides a useful procedure for assessing and prescribing high-intensity interval training for rugby athletes.
克莱默，M，克拉克，IE，贾米尼克，N，斯特罗姆，C，和佩蒂特，RW。高水平男性橄榄球运动员的临界速度和 D'的正常值数据。J 力量与调节研究 32（3）：783-789，2018-临界速度（CS）概念有助于描述运动员的有氧和无氧适应性。假设橄榄球运动员的 CS 值应该适中，但 D'值（曲率常数）极高，但目前还没有正常值数据。为了为高水平男性橄榄球运动员制定 CS 和 D'的正常值数据，总共从南非东开普省招募了 30 名男性橄榄球运动员。所有受试者均使用全球定位系统（GPS）技术进行 3 分钟全力跑测试（3 MT），以确定 CS 和 D'。GPS 数据用于确定总距离和速度，并检查节奏效果。提供了均值±SD 的摘要统计数据。前 150 秒的总跑步速度较高（S150s = 5.79 ± 0.59 m·s），总距离（3 MT 距离= 871.5 ± 71.9 m）。共有 30 名受试者中的 13 名超过了 300 m D'值（平均 D'= 288.2 ± 49.1 m）。总组的 CS 为 3.87 ± 0.55 m·s。所有 3 MT 衍生数据均使用标准九（斯坦因）表进行分类，这允许生成正常值数据，以便将来的表现、类似运动领域的表现以及更准确地进行文献对比。在前锋和后卫之间观察到 CS 和 D'的偏斜，因此，CS 和 D'均未观察到组间差异（p > 0.05）。与之前的文献相比，男性橄榄球运动员的 CS 值高于女性橄榄球运动员。与奥运会距离跑运动员相比，男性橄榄球运动员的 D'值明显较高，CS 值明显较低。3 MT 为评估和规定橄榄球运动员的高强度间歇训练提供了有用的程序。
